There is a need to develop stimulated learning enviroments in the organisation at Hagen school. We want to strengthen the quality of our outdoor lessons and get more methods to to be able to teach outdoors in a inspired and creative way. This because we want to teach more mathematics and also other subjects, in order to inspire the young students. There is a need to have collective thinking in the organization about mathemathics. And the education in the preschool will become the platform of outdoor learning in the whole organization. The school has students in the age from 6 to 13 years. We have started a project to develop mathematic in different levels from our policy documents. The projekt aim in our school is to develop and enhance the quality of teaching through ourdoor didactics. All teachers have undergone or are undergoing training in math didactics. In order to increese our quality of our education we will apply to an outdoor learning course. We believe that this is an excellent forum for children to learn mathematics. Through this course we are applying for, we will be able to develop this area in a new and creative way with different methods , leading to a united approach at Hagen School. By having half classes outdoors, we can individualize lessons and facilitate the attainment of the objectives of the curriculum and guidelines regarding the school. With greater knowledge of outdoor education, we can exploit the local environment for lessons outdoors. We belive that a collective thinking will join us together in the school. It will make it easier to reach the city of Göteborg International Strategy for education and although Gothenburg's plan regarding school, mainly covering stimulating environments Our school reaches for develop a united approach. The preschool are an important base for future knowledge and have to incooperate in this work to achieve future results in mathematics and other topics. We will with this project be included in the context of our school and achieve these specific goals.
